Can CT scan detect HCC?
The American Association for the Study of the Liver (AASLD) recommends contrast computerized tomography (CT-scan) and magnetic resonance (MRI) to diagnose hepatocellular carcinoma (HCC) arising in cirrhotic patients under semiannual surveillance with abdominal ultrasound (US)..
What is a computed tomography of the liver?
A CT scan of the liver and biliary tract may be performed to assess the liver and/or gallbladder and their related structures for tumors and other lesions, injuries, bleeding, infections, abscesses, unexplained abdominal pain, obstructions, or other conditions, particularly when another type of examination, such as X- .
What is HCC in CT scan?
On CT, HCC generally appears as a focal nodule with early enhancement on the arterial phase with rapid washout of contrast on the portal venous phase of a three-phase contrast scan.
MRI of HCC generally demonstrates high signal intensity on T2 imaging..
What is the best imaging for HCC?
Cross-sectional imaging with computed tomography (CT) scanning and magnetic resonance imaging (MRI) is most commonly used to detect hepatocellular carcinoma (HCC)..
What is the best imaging for HCC?

What is the CT finding in HCC?
Classic CT findings of HCC include a hypervascular pattern with arterial enhancement and rapid washout during the portal venous phase. (See the images below.) In contrast, regenerative nodules generally appear isoattenuating or hypoattenuating when compared with the remaining parenchyma..
What is the imaging for HCC screening?
In the context of HCC surveillance, multiphase abdominal MRI may take approximately 40 minutes to complete and US may take approximately 30 minutes; whereas, an abbreviated MRI protocol is typically performed in 15 minutes or less and includes only the sequences necessary for detection of HCC..

What is the role of CT in HCC?
The Liver Imaging Reporting and Data System offers a standardized nomenclature for reporting CT or MRI liver findings among at-risk patients.
Finally, cross-sectional imaging plays a critical role for assessing response to any HCC therapy as well as monitoring for HCC recurrence in those who achieve complete response..
Where is hepatocellular carcinoma located?
Liver cancer begins in the liver cells.
The most common type of liver cancer starts in cells called hepatocytes and is called hepatocellular carcinoma.
Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer..
- Hepatic Ultrasound: Hepatic ultrasound, when performed by an operator with expertise, has a sensitivity of 60 to 80% and specificity greater than 90% for overall detection of HCC at any stage.
- Hepatocellular Carcinoma (HCC) is the major form of liver cancer.
Risk factors for HCC include chronic HBV (hepatitis B virus) and HCV (hepatitis C virus) infections, autoimmune hepatitis, chronic alcohol use, obesity and diabetes mellitus etc [2]. - In the context of HCC surveillance, multiphase abdominal MRI may take approximately 40 minutes to complete and US may take approximately 30 minutes; whereas, an abbreviated MRI protocol is typically performed in 15 minutes or less and includes only the sequences necessary for detection of HCC.
- Liver biopsy remains a reliable diagnostic tool for HCC and includes different modalities, with percutaneous, ultrasound-guided liver biopsy as the most common method due to its cost-effectiveness and speed.
- The rationale for screening for hepatocellular carcinoma (HCC) is based on the concept that populations at high risk for HCC, such as those with cirrhosis, can be identified.
However, 20% to 50% of patients presenting with HCC have previously undiagnosed cirrhosis.
